Atomic Structure

HideShow resource information

Electron relative mass - 1/2000

ISOTOPES ARE ATOMS OF THE SAME ELEMENT (SAME NUMBER OF PROTONS) WITH DIFFERENT NUMBER OF NEUTRONS.

  • Isotope symblo (Hydrogen-1) indicated number of neutrons (mass number)
  • Loose electrons = Positive Ion
  • Gain Electrons = Negative Ion

RELATIVE  ISOTPIC/ATOMIC/MOLECULAR/FORMULA MASS IS THE MASS OF AN ISOTOPE/ATOM/MOLECULE/FORUMLA OF IONIC
